Reading Event Time
Stamps
Each alarm condition has an associated time stamp. This
time stamp tracks the most recent occurrence of the out-of-
tolerance condition. The time stamp indicates the earliest
time at which the most recent out-of-tolerance condition
was detected.
In general, the time stamps may be read using a query of
the form:
<attribute>:ALARM:TIME?
-- read the time
of the event
<attribute>:ALARM:DATE?
-- read the date
of the event
Where <attribute> is replaced by a keyword which indicates
which attribute’s out-of-tolerance time stamp is to be read.
The valid queries are:
VOLT1:ALARM:TIME?
-- +5V PS voltage alarm
VOLT2:ALARM:TIME?
-- -5.2V PS voltage alarm
